Yep! But you are also a mouse who has limited venues in which to complain.

I wonder if the vaccine causes inflammatory and other unpleasant responses when administered. If so, I wonder if those responses go away after the last dose, when the three months of protection begin.

Here are the two paragraphs that I found interesting:

> The new vaccine, for now known as GLA-3M-052-LS+OVA, mimics the T cell signals that directly stimulate innate immune cells in the lungs. It also contains a harmless antigen, an egg protein called ovalbumin or OVA, which recruits T cells into the lungs to maintain the innate response for weeks to months.

> In the study, mice were given a drop of the vaccine in their noses. Some recieved multiple doses, given a week apart. Each mouse was then exposed to one type of respiratory virus. With three doses of the vaccine, mice were protected against SARS-CoV-2 and other coronaviruses for at least three months.

> It also contains a harmless antigen, an egg protein called ovalbumin or OVA

Here's hoping the final product doesn't have a side-effect of inducing an allergy to the main component of egg-whites.

Although even if that happened... Would it only apply to the raw materials, as opposed to cooked products where the ovalbumin was denatured by heat?

Edit: No, wait! What about "safe to eat" cookie-dough, which uses heat-treated flour and pasteurized eggs as ingredients!? The might still have intact ovalbumin, and obviously I can't give it up.
